When EMS was applied, it was found that 2.0% EMS resulted the highest microkernel rate (15.6‰). Treating the materials with 2.0% EMS for 4 hours could lead to semi-lethal. Cytological observations found that chromosome aberration phenomena such as single microkernel, double microkernel, three microkernel, chromosome bridge, resort chromosome and syncytium were presented in the mutants.

EMS诱变途径中，浓度为2.0 %处理时间为4 h的组合获得最高的微核率（15.6‰），EMS浓度为2.0 %处理时间为4 h的组合使材料达到半致死；细胞学的观察看到了单微核、双微核、三微核、染色体桥、滞留染色体和合胞体等染色体畸变现象，再生苗中发现了1棵变异株。60Co辐射的诱变途径中，20Gy的剂量使不定芽半致死，再生苗中发现了1棵变异株。

The recombinant virus still propagated in subcutaneous tumors, causing total regression and sustained viremia, but could not replicate in cells expressing complementary miRNAs and therefore did not cause myositis.

重组的病毒在皮下组织里具有正常的活性，能引发小鼠致死性的肌炎，和病毒血症。但是，在表达肌肉组织特异microRNA的细胞里，重组病毒无法复制并且不引起致死性的肌炎。

"The rate of tularemia or 'rabbit feer' infection has significantly declined since the 1940s. Howeer, the bacteria would be ery deadly as an aerosolized terrorist weapon -- inhaling as few as 10 bacteria could be potentially deadly," said Allen, who also is a staff researcher with the eterans Affairs Iowa City Health Care System.

"野兔病和'兔热病'的感染几率自从1940s以来明显的下降，但是，这种细菌可以成为一种具有强致死性的雾化器恐怖武器—只要吸入10个细菌就可能致死，"Allen说，他也是一位艾奥瓦城的退伍军人卫生保健系统的医学研究员。

There are experimental results as follows:(1) Eriophorum comosum Nees shows strong cold resistance in plasmalemma permeability research. The lethal temperature of Eriophorum comosum Nees is the lowest LT_(50 in comparison with another two plants and is lower than -11.5℃ in August 2005 and December 2005; Soluble protein content of each plant is rising before or after cold hardiness. By SDS-PAGE, Protein band is analysed. Band quantity of Eriophorum comosum Nees is the most and its band color is darkest.(2) Soluble sugar content of three plants after cold hardiness are higher than before cold hardiness, moreover soluble sugar content after cold hardiness shows a decline and there is a narrow range in Eriophorum comosum Nees; Free Proline accumulation is changed by cold stress, and cold resistance is relative to free Proline accumulation; chlorophyll content of both three plants, including chlorophyll a, chlorophyll b and chlorophyll a/b, show a decline tendency along with the descent of temperature. Cynodon dactylon is highly sensitive to cold stress.(3) The soil POD and urease activities' absolute value of Erioophorum comosum Nees and Pogonatherum panideumHack were more than that of Cynodon dactylon before or after low temperature stress, especially POD activities.

实验结果表明：(1)在膜透性的研究中，丛毛羊胡子草抗寒性最强，采用电导率法测得半致死温度LT_(50最低，丛毛羊胡子草抗寒锻炼前后半致死温度LT_(50均小于-11.5℃；在可溶性蛋白含量研究中，抗寒锻炼前后三种植物的可溶性蛋白含量均增加，同时采用SDS-PAGE法，通过对蛋白条带分析，以丛毛羊胡子草条带数最多且着色深；(2)在可溶性糖的研究中，三种植物经抗寒锻炼后叶片可溶性糖含量都比抗寒锻炼前高，且经过抗寒锻炼后三种植物可溶性糖均呈下降趋势，丛毛羊胡子草可溶性糖含量下降较小；从游离脯氨酸含量可知，低温的胁迫影响了植物叶片游离脯氨酸的含量变化，植物的抗寒性与游离脯氨酸有关；低温胁迫下三种植物叶绿素含量随着温度的下降，叶绿素含量、叶绿素a、叶绿素b和叶绿素a／b均呈下降趋势，狗牙根对低温胁迫最为敏感；(3)低温锻炼前后，丛毛羊胡子草和金发草的土壤过氧化物酶与脲酶活性的绝对值均大于狗牙根的，特别是过氧化物酶，说明丛毛羊胡子草和金发草的酶活性大于狗牙根的。

After twenty-one days, they were challenged by white spot syndrome virus. The mortalities of crawfishes after challenged with WSSV of the same dilutions were negatively correlated with the the dose of Ig-Guard, that is, along with the increase of the dose of Ig-Guard, their mortalities were decline; The LD50 of the immune group was higher than the control group, further more, along with the increase of the dose of Ig-Guard, the effectes were obvious.

注射相同稀释浓度的螯虾，其死亡率与添加Ig-Guard的剂量呈负相关，即添加Ig-Guard剂量越高，其死亡率越低；免疫组螯虾的半数致死剂量(LD50)高于对照组的半数致死剂量，而且其效果随着免疫剂量的增加而越来越明显。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
